“…ovalis and Balanion comatum (Fig. 2i), nano-sized ciliates probably play an essential role at Helgoland Roads by feeding on bacteria and picophytoplankton which are too small to be used by larger ciliates (Sorokin et al 1996;Zingel et al 2007).…”

“…In the second monitoring, according to the recent study by Garcia-Cuetos et al (2012), the smaller one (15 lm) was assigned to the species M. rubrum and the larger one (35 lm) was assigned to the species M. major. They have been recorded in all oceans of the world from polar regions to equatorial latitudes (Edwards and Burkill 1995;Sorokin et al 1996;Pérez et al 2000;Mironova et al 2009;Wickham et al 2011;Löder et al 2012), and they are the most abundant and frequent ciliates at Helgoland Roads. M. rubrum (Fig.…”

“…and L. strobila, which are typical of many coastal and oceanic waters including the Irish Sea (Edwards and Burkill 1995), the southern North Sea (Steif 1988), the Baltic Sea (Mironova et al 2009), the Irminger Sea (Montagnes et al 2010), the Bering Sea and North Pacific (Sorokin et al 1996). As in many other coastal waters, M. rubrum and M. major are very important components of the ciliate community at Helgoland Roads.…”

“…As in many other coastal waters, M. rubrum and M. major are very important components of the ciliate community at Helgoland Roads. Similarly, on the northwest shelf of the Bering Sea, up to 30-40 % of the ciliate community was comprised of M. rubrum (probably the mixture of M. rubrum and M. major, Sorokin et al 1996). In the Bornholm Basin (the southern part of the central Baltic Sea), they dominated the microzooplankton communities in spring and early summer with a biomass 200-300 lg C L -1 (Mironova et al 2009).…”

This study presents a new checklist of ciliates at the long-term sampling station Helgoland Roads. The work is based on a microzooplankton monitoring programme from January 2007 to June 2009 and a ciliate monitoring programme from June 2010 to May 2012. The checklist includes 89 ciliate taxa from 46 different genera. The total abundance of the ciliate community at Helgoland Roads ranged between 0.14 and 67.7 9 10 3 cells L -1 with a distinct peak in June. The total carbon biomass ranged between 0.2 and 234.6 lg C L -1 . The ciliate community showed a clear temporal succession pattern during the monitoring periods. The present study is not only the first detailed and updated list of ciliates at Helgoland Roads, but also provides information on seasonality, i.e. the temporal variation of species composition, abundance and carbon biomass as well as information on the biogeographic distribution of dominant ciliates in comparison with other relevant studies.

“…Le métazoo-plancton peut avoir, selon la saison ou l'écosystème, les protozoaires ciliés comme principale source de nourriture, en remplacement du phytoplancton qui peut s'avérer inadéquat (SOROKIN, 1996). Différents auteurs ont souligné l'importance de l'impact des Copépodes sur les protozoaires ciliés en milieu marin (STOECKER et MC DOWELL-CAPUZZO, 1990) et en milieu lacustre (e.g.…”

L'impact du zooplancton métazoaire sur le phytoplancton et les protozoaires ciliés a été mesuré durant la période de juillet à décembre 1999 dans le réservoir Sahela sous climat méditerranéen semi-aride.Les expériences ont été réalisées à l'aide de chambres de diffusion immergées in situ pendant 7 heures en absence (chambres témoins) et en présence (chambres expérimentales) du zooplancton.Les résultats indiquent que la mortalité moyenne à 4 m des algues est de 0,13 + 0,03 h-1, et celle des protozoaires ciliés de 0,07 + 0,03 h-1. Cryptomonas ovata et Halteria grandinella ont subi la plus forte prédation, respectivement, 0,31 + 0,14 h-1 et 0,11 + 0,04 h-1 à 4 m. Toutefois, les algues de grande taille (Pediastrum sp, Ceratium hirundinella et Peridinium cinctum) n'ont été que très peu ou pas consommées.The Sahela reservoir, located in Taounate at 90 km from Fès, lying at an altitude of 325 m, was built to provide drinking water for the population of Taounate and to contribute to irrigate neighbouring farming perimeters.In order to assess the impact of metazoan zooplankton on phytoplankton and protozoan ciliates in the Sahela reservoir under semi-arid climate, we conducted experiments during the period from July to December 1999 at the deepest point in the lake (15 m).Sampling and measurements were carried out in diffusion chambers submerged in situ over a period of 7 h without (control chambers) and with (experimental chambers) zooplankton. During these experiments, counts were conducted on phytoplankton and ciliates to determine the abundance and the mortality of these organisms due to zooplankton in each diffusion chambers at t=0 and t=7 h incubation. The metazooplankton were counted and dry weight of each taxa was calculated.In summer the highest zooplankton biomass (150 µg·L-1) mainly composed of cyclopoid Tropocyclops prasinus, caused mortality of the small-sized ciliates, such as Halteria grandinella (0.10 h-1). In Autumn, the zooplankton biomass (75 µg·l-1), dominated by Daphnia longispina, induced a higher mortality for phytoplankton (0.10 h-1) than for ciliates (0.05 h-1). In Winter, the zooplankton biomass (100 µg·L-1), also represented by Daphnia longispina, had a low impact on ciliate mortality (< 0.02 h-1).The study showed that a heavy predation by the metazoan zooplankton was exerted on small-sized phytoplankton and ciliates and clearly demonstrated the relationships between protozoans and metazoan zooplankton to transfering the matter and energy in aquatic food webs
